Arguments

object

an object for which a summary is desired.

x

a result of the default method of summary().

maxsum

integer, indicating how many levels should be shown for
factors.

digits

integer, used for number formatting with
signif() (for summary.default) or
format() (for summary.data.frame). In
summary.default, if not specified (i.e.,
missing(.)), signif() will not be called
anymore (since R >= 3.4.0, where the default has been changed to
only round in the print and format methods).

...

additional arguments affecting the summary produced.

Details

For factors, the frequency of the first maxsum - 1
most frequent levels is shown, and the less frequent levels are
summarized in "(Others)" (resulting in at most maxsum
frequencies).

The functions summary.lm and summary.glm are examples
of particular methods which summarize the results produced by
lm and glm.

Value

The form of the value returned by summary depends on the
class of its argument. See the documentation of the particular
methods for details of what is produced by that method.

The default method returns an object of class
c("summaryDefault", "table") which has specialized
format and print methods. The
factor method returns an integer vector.

The matrix and data frame methods return a matrix of class
"table", obtained by applying summary to each
column and collating the results.
